T aZZ whom it may concern:

Be it known that 1, MAX I STADTMULLER, a citizen of the United States ofAmerica, and a resident of Pomeroy, Calhoun county; Iowa, have inventedcertain'new and useful Improvements in Attached Swinging Straw- Stackers, of which the following is a specification.

The object of this invention is to provide improved means for stackingstraw. i

This invention has relation to stacker attachments for separators, andhas for its objects to combine with the sectional, fold able, andadjustable stacker novel means, for strengthening and holding thesections of the stacker in alinement; adjusting mechanism cooperatingwith the stacker and itsbracing stacker, maintaining its sections inalinement when unfolded, and raising and lowering the outer end of thestacker; mechanism for oscillating, locking, andreleasing-the stacker,and means for relieving the shock incident to folding of the stacker,all the adjunct-ive parts being combined and arranged with a view toeconomy of space, positiveness of action, ease of operation, andaccessibility for any desired purpose. H

The invention further consists of the novel features, details ofconstruction, and combi nations of the parts, which will hereinafter. bemore fully set-forth, claimed, and illus: trated in the accompanyingdrawings, in which j v Figure 1 is a side elevation of the completemachine.

arator, the inner end of the stacker, and the cooperating mechanism on alarger scale.

In the construction, mounting, and operation of the machine, asillustrated, the numeral 1O designates a separator having the usualcylinder-shaft 11, with a belt-wheel 12 on one end thereof. A frame 13is mounted horizontally on and projects from the end of the separator atwhich the straw is discharged and is located in the horizontal plane ofthe rear trucks of the separator. Standards 14 15-1617 are mounted onand rise from the frame 13, and antifriction-rollers 18 are pivoted onthe upper ends of said standards, the standards being arranged at equaldistances of separation. A turn-tablel9 is mounted horizontally andrests on the antifriction-rollers 18. A bed-frame 20 is mountedhorizontally and secured by posts 20 to and upon the turntable 19 Ashaft21 is mounted for'rotationin bearings 22 23, rearwardly projectingfrom the rear corners of the bed-frame 20, and said shaft projects atboth ends beyond its bearings. H in ge-plates 24: 25 are mounted forrevolution on the projecting end portions of the shaft 21, and astacker-frame is rigidly attached at its inner (lower) end to saidhinge-plates. The stacker-frame is formed into sections 26 27,connectedby hinges 28 29 in such a manner that the upper (outer) section 27 willfold for wardly and upon the lower (inner) section 26. Braces 30 31 arefixed to and project rearwardly and downwardly from the section 26 ofthe stacker-frame, and the outer extremities of said braces arein aplane between the ends of said section 26 of the frame. Braces 32 33arefixed to and extend forwardly and downwardly from the section 27ofthe stackerframe, and the extremities of said braces project beyondthe hinged end of said section 27 and are arranged and so shaped as toabut the rearward extremities of the braces 30 31 and supportortrussthesectionsof the stackerframe in alinement with each other, asillustrated in Figs. 1,2, and 3 of the drawings. Ears 34 35 are fixed toand project downwardly from the extremities of the braces 30 31 and areformed with eyes or apertures, to which the rear ends' of cables 36 37are attached.

Sheaves are mounted in brackets 38 39 on the extremities of the braces32 Sheaves are mounted in brackets 40 41 on the extremities of thebraces 30 31 adjacent the ears 34 35, and sheaves are mounted inbrackets 42 43, fixed to the hinged ends of the section'26 of thestacker-frame, and the cables 36 37 extend from points of attachment tothe ears and through said sheaves in sequence-that is to say, the cable36 successively runs through the sheaves in the brackets 38 4O 42 andthe cable 37 successively runs through the sheaves in the brackets 39 4143. A socket 44 is mounted on and rises from the top of the rear endportion of the separator 1.0-and is braced to said separator by rods 45.A shaft 46 is stepped in the socket 44, and a cross-head 47 is rigidlymounted on the upper end of said shaft and extends transversely of theseparator, the length of the cross-head being approximately the same asthe width of the stacker-frame. Sheaves are mounted in brackets 48 49 onthe upper face of the crosshead 47, and sheaves 5O 51 are mounted in abracket'52, centrally located on the upper face of said cross-headbetween the brackets 48 '49. The cables 36 37 are run through thesheaves in the brackets 49 48 and thence through the sheaves 51 andextend forwardly in approximately parallel planes above the median lineof the separator 10. A shaft 53 is mounted for rotation on a horizontalaxis in bearings fixed to and rising from the separator 10 and extendstransversely of said separator, one end portion of said shaft projectingbeyond one side of the separator a material distance and having mountedthereon a worm-gear 54. A worm-shaft 55, having a worm 56 thereon andintermediate of its ends, is mounted for rotation on a vertical axis inbearings 57, fixed to and projecting laterally from the frame of theseparator. The worm 56 meshes with the worm-gear 54 on the shaft 53, andhand-wheels 58 59 are fixed to the end portions of the worm-shaft 55, bymeans of which hand-wheels manual power may be applied to rotate thewormshaft and drive the drum-shaft 53 in either direction. Drums 6O 61are mounted rigidly on the central portion of the drum-shaft 53,

andthe forward end portions of the cables 36 37 are fixed to and adaptedto be wound upon said drums. A bearing 62 is fixed to and rises from thetop of the separator 10 between the adjacent ends of the drums 61.Levers 63 64 are fulcrumed at their lower ends on the bearings 22 23 andextend upwardly therefrom. Ears 65 66 are formed on and projectoutwardly from the forward ends of the bearings 22 23, and curved rods67 68 are mounted rigidly by means of jamn'uts at their upper ends onthe upper ends of the levers 63 6t, and the lower end portions of saidcurved rods extend through apertures in the cars 65 66 and are providedwith split keys transversely mounted therein below said ears. Expansivecoiled springs 69 70 are mounted on the curved rods 67 68 above the ears65 66, and the tension of said springs is regulated and determined byadjusting-nuts 71 72 on the rods engaging the upper (outer) ends of thesprings. Bearings 73 74 are mountedon and rise from the corners of theseparater-frame laterally removed from the socket 44, and a rock-shaft75 is mounted therein. The extremities of the rock-shaft 75 are bentrearwardly at right angles to the intermediate port-ion of said shaftand formed with hooks 76 77 at their outer ends. A crank-arm 78 isformed on and rises from the rock-shaft 75, adjacent the bearing-73, anda rod 79 is pivoted at one end to the extremity of said crankarm andextends therefrom forwardly of the separator, transverses a slide-bearing 80, fixed to and rising from the separator adjacent the drum-shaft 53,and terminates in a handheld or eye 81. Angle-irons 82 83 are fixed toand extend forwardly and upwardly from the section 26 of thestacker-frame adjacent the upper (outer) end thereof and in suchpositions as to engage the hooks 76 77 of the rock-shaft 75 when thestacker-frame is swung forwardly for folding upon the separator. A shaft84 is mounted for rotation in and transversely of the outer end of thesection 27 of the stackerframe, and a shaft 85 is mounted for rotationin the lower corners of the bearings 24 25, extends transversely of thestacker-frame parallel with the shaft 84, and projects beyond one of itsbearings. A bottom 86 is positioned in the stacker-frame, and an endlessstrawcarrier 87 is mounted for travel on the shafts within thestacker-frame and driven by the shaft 85, the cleats 88 of thestraw-carrier traveling upwardly and outwardly in contact with the upperface of the bottom 86. A shaft 89 is mounted horizontally in andtransversely of one end of the bed-frame 20, parallel with the shaft 21,and an endless straw-carrier 90 is mounted for travel on the shafts inthe bedframe and driven by the shaft 21, the cleats 91 of the carrier 90traveling rearwardly and outwardly in contact with a bottom 92 in saidframe. A plate 93 is horizontally positioned on the central portion ofthe frame 13 and is centrally apertnred. A worm-gear 94 is stepped forrevolution on the plate 93 concentric with the aperture in said plateand is located horizontally between the turn-table 19 and said plate. Ashaft 95 is vertically positioned in the aperture in the center of theplate 93 and the turn-table 19, and a miter-- wheel 96 is mountedrigidly on the upper end of said shaft and the hub of said miter-wheelrests on a steel wear-plate 97, surmounting a boss 98 on the centralportion of the turn-table. As hereinbefore stated, the bed-frame 20 isconnected by the posts 20 rigidly to the turn table. Ears 99 100 arefixed to and rise from the turntable 19 and are apertured horizontally,and a shaft 101 is pivotally mounted in the apertures of the ears 99 100and extends approximately radially of and from the turn-table 19 to apoint beyond one side bar of the frame 13, and the outer end portion ofsaid rock-shaft is provided with the crank-arm 102.

a crank-arm 102, to which a cable 103 is attached by one end, the cable103 extending horizontally along the side bar of the frame 13, andthence through eyes 104, projecting from the stacker-frame to the outer(upper) end of said stacker-frame, at which point the cable is providedwith a handhold or loop 105. A pawl 106 is fulcrumed at one end on oneside bar of the frame 20 andis arranged and so shaped as to engage attimes with the crankarm 102 on the rock-shaft 101 and limit the movementof oscillation of said shaft in one direction. A torsional coil spring'107 is mounted on the rock-shaft 101 between the cars 99 100, and abifurcated crank-arm 108 on said shaft adjacent the ear 99 is engaged byone end of said spring, the opposite end of said spring engaging theturn-table 19 or a spoke thereof. The tension of the spring 107 tends tobear the bifurcated arm 108 downwardly and oscillate the rock-shaft inone direction and in a direction opposite to the movement that would begiven the rockshaft bydraft of the cable 103. A pin 109 is mountedvertically in an aperture in the turntable 19 and engages normally inone or another of a series of apertures 110 in the wormgear 94. The pin109 is formed with an annular groove near its upper end of such size asto receive the arms of the bifurcated crankarm 108. The pin 109 normallylocks the turn-table 19 and worm-gear 94 together, but may be liftedaway from the worm-gear by manual oscillation of the rock-shaft 101,either through draft applied to the cable 103 by an operator located onthe straw-stack or at the discharge end of the stacker-frame or by anapplication of manual force directly to Upon the release of. the manualforce applied to the rock-shaft the spring 107 will reverse the movementof said shaft and permit the seating of the pin 109 in one or another ofthe apertures or seats 110 inthe worm-gear. A curved crank-arm 111 isfixed to and projects forwardly from the rock-shaft 101 approximatelyparallel with the crank-arm, and it is the function of the arm 111 tooscillate the shaft automatically in the same direction that said shaftmay be oscillated by manual force and such automatic movement is givenby the engagement of the arm with one oranother of studs 112 113, fixedto and rising from bars 114 115 of the frame 13. A shaft 116 is mountedfor rotation in bearings 117 118, fixed to the frame 13, and asprocket-wheel 119 is rigidly mounted on one end of said shaft outsidesaid frame. A shaft 120 is mounted for rotation in bearings fixed to theframe 13, and a sprocketwheel 121, rigidly mounted on said shaft, isconnected by a chain 122 to the sprocketwheel119. A belt-wheel 123 isrigidly mounted on the outer end portion of the shaft 120 and connectedby a belt 124 to the belt-wheel 12 on the cylindershaft 11. The shaft120 extends nearly to the center of the frame 13, and a miter-gear 125is mounted rigidly on the inner end thereof and meshes with a mitergear126, rigidly mounted on the lower end of A counter-shaft 127 iscounter-shaft 127 and connected by a chain 130 to a sprocket-wheel 131on the shaft 21 adjacent the bearing 22. A sprocket-wheel 132, alsomounted rigidly on the shaft 21, adjacent the sprocket-wheel 131, isconnected by a chain 133 to a sprocket-wheel 134 on the extremity of theshaft 85 adjacent thereto.

The rotary movement of the cylinder-shaft 11 is communicated, throughthe belt-wheel 12, belt 124, belt-wheel 123, shaft 120, mitergear 125,miter-gear 126, shaft 95, miter-gear o 96, miter-gear 128, shaft 127,sprocket-wheel 129, chain 130, sprocket-wheel 131, shaft 21,sprocket-wheel132, chain 133, sprocket-wheel 134, and shaft85, to anddrives the strawcarrier 87 in the stackerframe.

municated, as described, to the shaft 21, drives the straw-carrier inthe bed-frame 20 in the same direction as the straw-carrier in thestacker-frame is driven. chain and wheel connection between the shaft120 and the shaft 116 drives said shaft 116 in the same direction as thecylinder-shaft is driven and in the direction of the arrow C6111 Fig. 5.on the shaft 116 adjacent to and just inside of one side bar of theframe 13 and meshes with a gear-wheel 136, loosely mounted on aworm-shaft 137, mounted for rotation in the bearings 117 118. 136 isformed with a clutch member arranged and so shaped as to engage at timeswith one face of a clutch member 138, slidably mounted on the worm-shaft137. The clutch member 138 is formed with a longitudinal that istraversed by a pin 140, seated in and projecting radially from theworm-shaft. lever 141, bifurcated at its rear end, is fulcrumed at itsforward end on the frame 13 A miter-gear 128 is mounted rigidly 75 Thesame rotary movement of the cylinder-shaft, com- The sprocket Agear-wheel 135 is mounted rigidly The hub of the gear-wheel I 10 beneaththe peripheral portion of the turnme table 19, and the bifurcated endportion of said lever embraces the clutch member 138 and is confined byperipheral flanges 142 143 on said clutch member. Thus is the clutchmember 138 mounted to rotate with the worm- 1 2 shaft 137 and slide uponand longitudinally of said shaft under the control of the lever 141,engaging one or another of the peripheral flanges 142 143. A clutchmember 144 is mounted loosely on the worm-shaft 137 and rigidlyconnected to a sleeve 145 to a gearwheel 146, mounted loosely on thewormshaft adjacent the bearing 118. The gearwheel 146 meshes with agear-wheel 147,

of the faces of the clutch member 138.

mounted on a stud projecting from the bearing 118 immediately below theworm-shaft 137, and the gear-wheel 147 meshes with the gear-wheel148 onthe inner end portion of the shaft 116, the gear148 and miter-gear beinglocated on opposite sides of the bearing 118. The clutch member 144 isso shaped and arranged as to engage at times with one A worm 149 ismounted rigidly on the inner end portion of the worm-shaft 137, thegear-wheel 146 and worm being located on opposite sides of the bearing118. It may be well to observe here that the worm 149 meshes with anddrives the'worm-gear 94, and the bearing 118 limits thelongitudinalmovementof the worm and its shaft. When the clutch member 138 is in theposition shown in Figs. 4 and 5, engaging the clutch member on the hubof the gear-wheel 136, a driving connection is established between thegears 136, clutch members, and Worm-shaft 137, whereby said worm-shaftis rotated in the direction of the arrows bin Fig. 4, resulting in amovement of revolution of the worm-gear 94 in the direction of the arrow0 in Fig. 4, whereby the worm-gear, turntable 19, connected thereto bythe pin 109, bed-frame 20, and mechanism carried by said bed-frame andincluding the stacker frame are revolved in such a manner as to carrythe stacker-frame in an arc toward and over the belt-Wheel 123 of thedriving mechanism and into a position nearly at right angles to thelongitudinal plane of the separator. When the limit of movement in thedirection just described has been reached, a pin 150, vertically seatedin one or another of a series of apertures 151 in the peripheral portionof the turn-table, engages the arm of a tripping-lever 152, verticallypositioned for oscillation in bearings 153 154, fixed to the frame13,and moves said lever in one direction. The tripping-lever 152 is formedwith a lateral bend or crank 155 in its upper portion, and a rod 156 ispivotally connected at one end to said lateral bend or crank, and saidrod is connected at its opposite end to the lever 141, adjacent thebifurcated end portion of said 1ever. When the pin engages the arm ofthe tripping-lever and oscillates said lever in the direction of travelof the pin, such movement of oscillation is communicated through thebend or crank of the lever and exerts a draft on the rod 156, resultingin a movement of the lever 141 into engagement with the peripheralflange 143 of the clutch member 138, whereby said clutch member 138 isreciprocated or moved longitudinally on the worm-shaft in such a manneras to release the engagement thereof from the hub of the gear- Wheel136and establish an engagement between the other end of the clutch memberand the clutch-face of the member 144. When the clutch member 138 isshifted into contact with the clutch member 144, the gear-wheel 136 runsidly, and the motion heretofore transmitted idly from the shaft 116through the gear-wheels 148 147 146 now becomes a driving motion, andowing to the interposition of the gear-wheel 147 between the gears ofthe shafts the motion of the worm-shaft 137 is reversed relative to itsprior motion, thus providing for a reversal of the movement ofrevolution of the worm-gear 94 and turn-table. The reverse movement ofthe turn-table and mechanism carried thereon is continued until thestacker-frame is swung laterally of the separator and projects from theside of the frame 13 opposite to the belt wheel 123. When limit ofdesired movement in the reversed direction is reached, a pin 157,vertically mounted in one or another of the aper tures 15l,en gages thearm of the tripping-lever 152, reversely moves said lever, and, operating through the bend or crank 155 and rod 156 pushes the lever 141 andclutch member 138 away from the clutch member 144 and toward thegear-wheel 136, thus restablishing the original movement of oscillationor rotary travel of the stacker frame. A crank arm 158 projectslaterally from the tripping lever 152 and is connected by a retractilecoilspring 159 to an adjusting-screw 160, seated in one side bar of theframe 13. The relative positions of the tripping-lever andadjustingscrew are such that the spring 159 tends to retain thetripping-lever in either position, at either limit of rotary movement,in which it may be placed by contact of one or another of the travelingpins 150 157. The pins 150 157 may be removed from or replaced in theapertures. or seats 151, as desired, to govern and control the degree ofmovementof oscillation of the stacker-frame between the operations ofreversing such movement or to determine the degree of oscillation of thestacker-frame laterallyof and relative to the median line of theseparator. It may occur that one or another of the pins 150 1.57 will beaccidentally displaced from its seat, and to avoid crashing thestacker-frame or driving mechanism into the frame of the separator Ihave provided the crank-arm 111 and studs 112 113, in the use of whichthe crankarm 111 will ride upon one orthe other of the studs and releasethe locking engagement of the pin 109 between the turn-table andwormgear in the event that for any reason the tripping-lever fails toreverse the driving mechanism whereby the worm-gear and turntable arerevolved. Again, it sometimes occurs that it is desirable to stop theoscillatory movement of the stacker-frame to deposit a greater quantityof straw in a given position, and for this reason I have provided thecrank-arm 102, cable 103, handhold 105, and pawl 106, the operations ofwhich hereinbefore have been explained. In the oscillation of thestacker-frame laterally the crosshead 47 oscillates inits step andcompensates for the slackening and tightening of the cables 36 37intermediate of their ends and maintains a level transverselypositioning of A hood 161, preferably the stacker-frame.

formed of sheet metal, is mounted rigidly upon and projects rearwardlyfrom the strawdischarging end of the separator and is supported in itscentral portion by one of the braces 45, connecting it to the socket 44.Bearings 162 are fixed to anddepend from the lower margin of the hood161, andahingerod is extended through and horizontallysupported by saidbearings. A plurality of leaves or wings 163 are mounted upon, hingedto, and depend from'the hinge-rod in the bearings 162 in close relationswith each other and abutting each other side by side. The leaves orwings 163 are arranged to swing outwardly relative to the hood 161 andpermit the discharge of the straw upon the carrier 90, while at the sametime they shield the straw and chad from the influence of air-currentsthat otherwise might scatter said straw and chaff and prevent thedischarge thereof by the straw-carriers. Hangers 164 165 are pivoted attheir upper ends upon and depend from the rear portion of theseparator-frame adjacent the ends of the hood 161, and a failings-frame166 is hung with its rear corners on the lower ends of said hangers.Bearings 167 168 are fixed to the forward corners of the tailings-frame166, and a rock-shaft 169 is mounted with its central (straight) bodyportion in a horizontal position beneath and transversely of the forwardend of the tailings-frame and embraced by bifurcations or forks on andextending downwardly from the bearings 167 168. Crank-arms 170 171 areformed on and extend downwardly from the rock-shaft 169 and are bentlaterally and journaled in bearings 172 17 3,proj ecting rearwardly fromthe separatorframe. .Thus is the rock-shaft journaled for oscillation inthe bearings 172 173 and carries the forward end of the tailings-frame,the rear end of the tailings-frame being suspended by the hangers 164165 loosely. Au extension 174 is formed on and projects downwardly fromthe crank-arm 170 and is bent inwardly at its lower end. A pitman 175 ispivotally connected at its inner end to the inwardly-extending portionof the extension 174 of the crank-arm 170 and extends rearwardlytherefrom to and is pivotally connected with a wrist-pin 176, mounted ona gearwheel 177, journaled on a stud 178, laterally projecting from aside bar of the frame 13, adjacent the sprocket-wheel121 on the shaft120. The gear-Wheel 177 meshes with a gearwheel 178, rigidly mounted onthe shaft 120 between the sprocket-wheel121 and the frame 13. The rotarymotion of the shaft 120 is communicated through the gear-wheel 178,gear-wheel177, wrist-pin 176, pitman 175', and extension 174 andconverted thereby to effect the oscillation of the rock-shaft 17 0,whereby the tailiugs-frame may be rectilinearly 1'eciprocated. Arock-shaft 179 is mounted in the bearings 167 168, extends transverselyof the forward end of the tailings-frame, and has a blade or wing 180mounted rigidly on one side of the tailings-frame.

and extending rearwardly and upwardly therefrom. A crank-arm 181 isformed. on one end of the rock-shaft 179, extends rearwardly at rightangles to said shaft, and has its rear end portion turned inwardly andso shaped and arranged as to seat in one or another of apertures 182 ina plate 183, fixed to A solid bottom 184 is mounted in thetailings-frame and projects forwardly into the fanchamber of theseparator. is mounted in the failings-frame immediately above and spacedapart from the solid bottom 184, and a series of ribs 185, of ratchetformation, are mounted on the screen and extend transversely of thetailings-frame. The tailin gs of chaff and grain that are blown from thefan-chamber upon the tailings-frame are sifted thereby, the chaff goingrearwardly over the ribs and upon the carrier 90 and the grain fallingthrough the screen upon the solid bottom 184 and discharging back intothe fan-chamber, below the main current of air therefrom. By means ofthe rock-shaft 179, blade 180, crank 181, and perforated plate 183 I amenabled to control, regulate, and determine the strength and directionof the current of air proceeding from the fanchamber of the separatorover the tailingsframe.

Shields 186 187 are mounted on and extend upwardly from opposite sides.of the bedframe 20 and serve to retain the straw against lateraldisplacement from the carrier 90.

Assuming the parts to be positioned as shown in Fig. 1, thestacker-frame may be folded upon the separator, as shown by dotted linesin Fig. 2, by the following operation: Manual force is applied to one oranother of the hand-wheels 58 59 to rotate the worm 56. The Worm 56engages and rotates .wormgear 54 toeffect the rotation of the worm-shaft53 and drums 61 thereon. The drums receive and wind up the forward endportions of the cables 36 37, and said cables, drawing through thesheaves on the crosshead 47, lift the stacker-frame on the axis ofrotation of the shaft 21. In the elevation of the stacker-frame the sidebars thereof contact With the levers 63 64 and are steadied andrestrained in further forward movement by said levers cushioning uponthe springs 69 and yielding under the draft of the cables only and notaffected materially by the forwardlytrending weight of the stackerframe. In its forward movement the stacker frame approaches the hood 161and the angleirons 82 83 travel beneath and engage the hooks 76 77 onthe rock-shaft 75. At this time the movement of rotation of thewormshaft 55 is reversed, thus slackening the cables and permitting thesection 27 of the stacker-frame to descend gradually and under perfectcontrol to a position of rest upon the top of the separator, the cablespaying out through the sheaves on the stacker-frame and permitting theseparation of the meeting A perforated slide or screen IIO ends of thebraces 30 31 32 33, the section 27 of the frame swinging on the pins ofthe hinges 28 29. When it is desired to elevate and extend thestackerframe, the worm mechanism is operated to first lift the section27 of the frame by draft upon the cables 36 37 until the braces of theframe contact, and. then the hooks 76 77 of the rock-shaft 75 arereleased from the angle-irons 82 83 by manual operation of the draw-rod79, acting through the crank-arm 7 6 to oscillate said rock-shaft, andthen the expansive resilience of the springs 69 impels the stacker-framerearwardly, subject to a succeeding manual relaxation of the cables 3637, until. the desired degree of inclination of the stackerframe isattained. The stacker-frame may be adjusted in any position between ahorizontal plane and the vertical plane for use; but its operation willbe more satisfactory when inclined to less than sixty degrees than itinclined to a greater extent than sixty degrees relative to a horizontalplane. The cylinder-shaft 11 of the separator may be driven in anydesired manner.
